I can only enter a numerical answer in box, please give me a number rounded to three decimals to enter in the box. Can you circle or bold this answer so I know what to enter. Thank you. I will rate your answer immediately. I tried "4" but as you can see this was incorrect.

Transcribed Image Text:The thin-walled hollow cylindrical member AB has a non-circular cross section of non-uniform thickness. Using the expression
T= 24 and the expression for the strain-energy density, determine the angle of twist of member AB, where ds is the length of a
small element of the wall cross section and A is the area enclosed by the center line of the wall cross section. (Round the final answer
to three decimal places.)
